Inventor: KUHN WILLIAM C
IPC: A61B3/107
Filed: 1995-02-24
Abstract: Procédé et dispositif de mappage de la surface d'un objet, notamment d'un objet transparent tel que les surfaces antérieure et postérieure de la cornée d'un patient, au moment souhaité, à l'aide d'un seul système optique. Dans un mode d'exécution préféré, un générateur de motifs (18) projette un motif lumineux et des zones sombres sur la cornée du patient (18) et un détecteur de lumière (14) reçoit les motifs réfléchis par les surfaces antérieure et postérieure (24, 28) de la cornée. Un organe de mappage (16) génère une carte tridimensionnelle des surfaces antérieure et postérieure (24, 28) de la cornée à partir d'informations relatives aux motifs lumineux projetés et détectés. On peut utiliser cette invention pour mapper d'autres objets, tels que des lentilles de contact ou un dispositif intraoculaire, par exemple un anneau intrastromal. On peut également l'utiliser pour mapper la surface d'un objet opaque.

Filed: 1995-03-20
Abstract: The invention concerns a method for the preparation of eucaryotic cell lines for the permanently ectopic expression of glutamate receptors, the cell lines being prepared by the transformation of cells containing nucleic acids coding for glutamate receptors. The method is characterized in that, during the establishment of the cell lines, at least one of the following conditions is satisfied for the culture: a) the transformed cells are cultured in a culture medium containing a glutamate precursor; b) the transformed cells are cultured in the presence of a glutamate-receptor antagonist: c) the transformed cells ant cultured in a first phase under conditions in which glutamate-receptor expression is repressed and in a second phase under conditions in which the repression is discontinued. The invention also concerns the cell lines thus obtained and their use.

Title: Bi-level charge pulse apparatus to facilitate nerve location during peripheral nerve block procedures
Inventor: GRIFFITH RICHARD LEE
IPC: A61N1/36
Filed: 1997-07-30
Abstract: An electrolocation apparatus is provided for locating a nerve to which anesthesia may be delivered. The apparatus includes a needle assembly having an electrically conductive needle cannula non-conductive tube secured over the needle cannula, and a conductive plating on the tube. The conductors are connected to astimulator that generates alternating high and low charge pulses with a constant low current level. The high charge pulses generate noticeable muscle twitches immediately after insertion of the needle into the patient. Muscle twitches responsive to the high charge pulses will peak in magnitude, and muscle twitchesresponsive to the low charge pulses will become observable as the needle approaches the targeted nerve, and will be indistinguishable from the muscle twitches responsive to the high charge pulses when the needle is in a position for administration ofanesthetic.

The vehicle according to the invention has a front frame (1) that is arranged onto a back frame (2) with a joint (3) of at least one degree of freedom that allows the rotation of the frames essentially with respect to the longitudinal axle of the vehicle. Furthermore, the front frame (1) has at least one axle (6) suspended so that it swings essentially with respect to the longitudinal axle of the vehicle.      Thus the mass to be moved with the equipment according to the invention is relatively small, whereby the need for hydraulic power in the equipment is not unreasonably great.

Filed: 1996-05-28
Abstract: The invention includes apparatus for processing an input signal to generate an output signal. The processing arrangement comprises first and second feedback loops for generating, from said input signal, respective output signal components. Each loop comprises a voltage controlled oscillator, having a frequency or phase which is variable in response to a control signal, for generating a loop output signal which forms one of the components of the output signal and a comparator for generating the control signal. There is also provided combining means for combining the loop output signals to derive a signal representative of the output signal. Means for providing first and second feedback loop operating signals, dependent on the output signal and in phase quadrature with one another are provided. In each loop, the feedback loop operating signal is applied to one input of the comparator and the other input of the comparator is coupled to receive a component of the input signal. Signal-stability means for continuously ensuring that the output signal is stable whatever the phase of the output signal relative to the input signal are provided. The signal-stability means and the comparators derive control signals v1 (I) and v2 (II) for the respective VCOs where k = the loop gain of the feedback loops, r = the amplitude of the input signal as represented by the components x and y, R = the amplitude of the output of the VCOs, .DELTA.x = the difference between the x component of the input signal and the corresponding Cartesian component of the processed output signal, and (.DELTA.y) = the difference between the y component of the input signal and the corresponding Cartesian component of the processed output signal.

Abstract: L'invention porte sur différents produits pour soins de la bouche à base d'ULTRAMULSION?TM¿ dont des dentifrices, du fil dentaire traité, des stimulateurs dentaires, des substances pour revêtements interdentaires, des bains de bouche, des produits de traitement interne de la bouche ou de la gorge, et des produits anti-gingivite. Tous ces produits peuvent être améliorés par adjonction d'une dispersion d'ULTRAMULSION?TM¿ contenant une silicone et un tensio-actif. De telles dispersions combinent certaines caractéristiques des émulsions et certaines caractéristiques des micro-émulsions. Comme les émulsions classiques, ces dispersions sont des systèmes à deux phases, c.-à-d. une silicone dispersée dans une phase continue de tensio-actif dans laquelle la silicone est insoluble, mais, contrairement aux émulsions classiques, elles présentent la stabilité des micro-émulsions. Contrairement aux micro-émulsions, mais, comme les émulsions classiques, leur formation demande un travail mécanique. Contrairement aux micro-émulsions, mais, comme les émulsions usuelles, ces dispersions ne se forment pas spontanément. Comme les émulsions classiques, ces dispersions ne contiennent pas de cosolvant, ce qui est par contre souvent le cas des micro-émulsions.
